The G Pen Pro Vaporizer is designed with an automatic shut-off feature to conserve battery life and prevent unnecessary heating. The G Pen Pro Vaporizer will automatically shut off after a four minute period because of this. If you would like to continue using the G Pen Pro after the automatic shut-off feature has gone into effect, simply press the power button five times to restore power and continue use.
If you have any further inquiries, please contact our Customer Service Department anytime Monday through Friday, 8:00am to 5:00pm PST.
